On-demand bundle analyzer, powered by esbuild.
This little terminal app exists because Bundlephobia and bundlejs are pretty cool and useful, but bundling locally and with offline support can easily work more reliably.
- Simple: the way this app works is super simple, it just generates the metadata file for the bundler analyzer in a temporary directory, embeds it inside the bundle analyzer itself, and opens it.
- Secure: postinstall scripts are disabled for security reasons, and only dependencies I personally maintain and
esbuildare used. - Available: unless NPM itself is unreachable, or esbuild can't bundle your modules, this bundle analyzer will always be available.
- Customizable: some important options, like the target platform or the target format, can be configured. Unlike in Bundlephobia where for many modules bundling will just fail.
- Offline support: esbuild's amazing bundle analyzer is embedded within the app, so the analysis can potentially even work if you are offline, if NPM has the modules you want to analyze cached already.
- Sharing support: a single HTML file is generated, specific to the analyzed modules, so it can be shared trivially.
